What Our Heating Service Includes
Heating systems work hard through long winter seasons, which is why thorough care makes such a difference. During a service visit, we perform a detailed inspection and tune-up to ensure your system is safe, efficient, and ready for cold weather.
Our service may include:
- Inspecting burners, heat exchangers, and ignition components
- Testing safety controls and electrical systems
- Checking blower motors and airflow
- Cleaning or replacing filters
- Verifying gas pressure and combustion efficiency (for gas furnaces)
- Confirming heat pump switching and defrost operation
- Testing thermostat accuracy
- Identifying early wear, efficiency loss, or safety concerns
After the visit, we review everything with you so you know the exact condition of your system — and what you can expect moving forward.
Heating Repairs You Can Count On
If your heat stops working, starts making unusual sounds, or isn’t keeping your home as warm as it should, our team is ready to help. We diagnose problems quickly and accurately so you don’t have to spend days in a cold house trying to guess what’s wrong.

No heat or inconsistent heating
Short cycling
